Oh yes, it's true then that life is good,
and I've learned the lesson it can teach:
that you can never have all you want,
and you never want what's within reach.

The MythPersephone, Greek goddess of the underworld, was the daughter of Zeus and Demeter. She was so beautiful that even Hades wanted her for himself, so he abducted her while she was picking flowers on the plain of Enna. None of the other gods noticed, save Zeus.

Demeter searched the earth, forlorn, until Helios, the all-seeing, told her about the abduction. Demeter withdrew in lonliness and anger, stopping all fertility on earth. Eventually Zeus sent Hermes to Hades to attempt to convince him to release Persephone. Hades agreed, but gave Persephone a pomengranate, thus permanently connecting her to the underworld, and forcing her to stay there for one-third of every year. While Persephone was in the underworld, Demeter refused to allow anything to grow, thus causing winter.
